Proton Exchange Membrane Requirements

Proton Exchange Membrane Requirements – PEM, Electrolyzer Coatings – Cheersonic

As one of the core components of the fuel cell, the proton exchange membrane can block the gas of the cathode and anode and the electrocatalyst of the cathode and anode, and the second is to selectively conduct protons and insulate electrons. In practical applications, the proton exchange membrane needs to meet the following points:

1 Has high proton conductivity, with a proton conductivity of at least 0.1S/cm.
2 has low electronic conductivity
3 It has good gas barrier ability and can ensure the efficiency of the battery in both dry and wet states.
4 Has a certain degree of chemical stability, that is, the structure of the paper exchange membrane can remain stable during the operation of the PEMFC
5 Has good thermal stability
6 Has good mechanical properties and dimensional stability, low swelling rate 7 Environmentally friendly, low price

The membranes currently under study mainly include: perfluorosulfonic acid proton exchange membranes, partially fluorinated proton exchange membranes, non-fluorinated proton exchange membranes, and composite proton exchange membranes.

Cheersonic’s ultrasonic spray fuel cell catalyst coating system can produce highly uniform, repeatable and durable coatings. Our ultrasonic spraying can well control coating properties, significantly reduce material usage, and reduce maintenance and downtime.

Our company’s ultrasonic spraying equipment can be sprayed on a variety of different metal alloys, including the preparation of platinum, nickel, iridium and ruthenium-based fuel cell catalyst coatings, as well as PEMs, GDLs, DMFCs (direct methanol fuel cells) and SOFCs (solid Oxide fuel cell) manufacturing. The battery manufactured by this technology has the characteristics of high battery load and high battery efficiency.
